In real ops, the airport CEO is responsible to close/ re-open the operations of the airport. Naturally, as you said, the CEO is a manager and not an emergency expert, so he would need to rely on his consultants/ managers.
As for the aircraft recovery part, the CEO might decide on the following options:
A: Recovery of the aircraft by the airport ops itself. This would result in less cost but in higher damage to the aircraft (if no proper equipment is available).
B: Aircraft recovery will be performed by a specialized company. This would lead to higher cost but less damage to the aircraft.
I imagine this is way too complicated and wont be implemented any time soon but keeping ideas documented is not a bad thing
